1、-MFC中ListControl控件的使用分类-第 12 页1. CListCtrl 风格 LVS_ICON: 为每个item显示大图标 LVS_SMALLICON: 为每个item显示小图标 LVS_LIST: 显示一列带有小图标的item LVS_REPORT: 显示item详细资料 直观的理解：windows资源管理器，“查看”标签下的“大图标，小图标，列表，详细资料”2. 设置listctrl 风格及扩展风格 LONG lStyle; lStyle = GetWindowLong(m_list.m_hWnd, GWL_STYLE);/获取当前窗口style lStyle &= LVS_

2、TYPEMASK; /清除显示方式位 lStyle |= LVS_REPORT; /设置style SetWindowLong(m_list.m_hWnd, GWL_STYLE, lStyle);/设置style DWORD dwStyle = m_list.GetExtendedStyle(); dwStyle |= LVS_EX_FULLROWSELECT;/选中某行使整行高亮（只适用与report风格的listctrl） dwStyle |= LVS_EX_GRIDLINES;/网格线（只适用与report风格的listctrl） dwStyle |= LVS_EX_CHECKBOXES

3、;/item前生成checkbox控件 m_list.SetExtendedStyle(dwStyle); /设置扩展风格 注：listview的style请查阅msdn3. 插入数据 m_list.InsertColumn( 0, ID, LVCFMT_LEFT, 40 );/插入列 m_list.InsertColumn( 1, NAME, LVCFMT_LEFT, 50 ); int nRow = m_list.InsertItem(0, “11”);/插入行 m_list.SetItemText(nRow, 1, “jacky”);/设置数据4. 一直选中item选中style中的Sh

4、ow selection always，或者在上面第2点中设置LVS_SHOWSELALWAYS5. 选中和取消选中一行 int nIndex = 0; /选中 m_list.SetItemState(nIndex, LVIS_SELECTED|LVIS_FOCUSED, LVIS_SELECTED|LVIS_FOCUSED); /取消选中 m_list.SetItemState(nIndex, 0, LVIS_SELECTED|LVIS_FOCUSED);6. 得到listctrl中所有行的checkbox的状态 m_list.SetExtendedStyle(LVS_EX_CHECKBOX

6、eteColumn (0) 因为你删除了第一列后，后面的列会依次向上移动。 方法二： int nColumns = 4; for (int i=nColumns-1; i=0; i-) m_list.DeleteColumn (i);13. 得到单击的listctrl的行列号 添加listctrl控件的NM_CLICK消息相应函数 void CTest6Dlg:OnClickList1(NMHDR* pNMHDR, LRESULT* pResult) / 方法一： /* DWORD dwPos = GetMessagePos(); CPoint point( LOWORD(dwPos), HI

8、* pNMListView = (NM_LISTVIEW*)pNMHDR; if(pNMListView-iItem != -1) CString strtemp; strtemp.Format(单击的是第%d行第%d列, pNMListView-iItem, pNMListView-iSubItem); AfxMessageBox(strtemp); */ *pResult = 0; 14. 判断是否点击在listctrl的checkbox上 添加listctrl控件的NM_CLICK消息相应函数 void CTest6Dlg:OnClickList1(NMHDR* pNMHDR, LRES

11、HIWORD(dwPos) ); CMenu menu; VERIFY( menu.LoadMenu( IDR_MENU1 ) ); CMenu* popup = menu.GetSubMenu(0); ASSERT( popup != NULL ); popup-TrackPopupMenu(TPM_LEFTALIGN | TPM_RIGHTBUTTON, point.x, point.y, this ); *pResult = 0; 16. item切换焦点时(包括用键盘和鼠标切换)，状态的一些变化顺序 添加listctrl控件的LVN_ITEMCHANGED消息相应函数 void CTe
